| Igneous rock as a special kind of reservoir in Liaohe basin,it has become one of the important exploration target,but because of igneous rock reservoir have space types,complex pore structure and strong heterogeneity,brought great difficulties to the research work of this paper.In this paper,the eastern sag of Liaohe depression in Hongxing area,the latest acquisition of the two wide one high(high,wide band,wide range and high density)seismic data as the foundation,by the synthetic seismic records combination of seismic and logging data seismic horizon calibration,and do seismic horizon calibration.Based on the theory of sequence stratigraphy,petroleum geology and structural geology,the comprehensive interpretation of seismic data in the middle section of Sha three in hongxing are.Based on the recognition and tracking of different cycles in different regions and the identification of coherent body auxiliary faults,the isochronous stratigraphic framework is established.Based on the introduction of the concept of seismic sequence,the igneous rocks in the middle part of the three member of Shahejie Formation in the area are divided into the following two cycles and four times,the corresponding structural features of each time are implemented.On this basis,using a variety of techniques,such as waveform clustering and attribute analysis,identification of igneous rock lithology and lithofacies of igneous rock distribution area in each time,the implementation of lithology and lithofacies;at the same time,according to the special situation of igneous rocks,the development of reconstruction can reflect the advantages of reservoir reservoir prediction curve,the curve the application of geostatistical inversion,predict reservoir body,identify the optimal reservoir;finally prestack OVT domain technique and poststack curvature analysis to predict the igneous rock fracture zone.On the basis of comprehensive analysis,the reservoir rocks of the selected target areas are divided into ?,?,?. |
